My period was three days late on the day it started it was spotting on tp only that night it got a little heavy but then next day barely on pad could have keep on the same one but gross to do that night a little heavy again, usually have period for three days then spot on the fourth day here it is day seven still spotting when I wipe no pad needed. Has anybody had this and what could cause it.. I have looked up implantation bleeding but it does not help does not sound like what I am doing.
